This pulsar was discovered by TRAPUM's Fermi Sources working group using MeerKAT, targeting the sky position of 4FGL J1356.6+0234. The pulsar was solved by Paulo Freire. For the gamma-ray follow-up, we used the orbital solution, the sky position (see plot below) and F0 from the radio timing analysis.
This binary pulsar was discovered and timed in gamma rays on 26 April 2023. More timing details can be found below.
Legend: Radio = gray, Gamma = green, isolated = cross or plus, binary = circle or square
